COUPLING FOR CULTIVATORS.

EBPECIPICATION forming part of Letters Patent No. 373,604, datedNovember 22, 1887.

A pplication filed March 25, 1887.

To aZZ whom it may concern.-

Be it known that 1, PETER RADER, of Kirklin, in the county of Clintonand State of In diana, have invented a new and useful Improvement inCouplings for Cultivators, of which the following is a full, clear, andexact description.

My invention relates to corn cultivators,and is a device for couplingthe shovel-beams to the arch of two-horse cultivators. Its objects areto provide light, strong, and inexpensive couplings adapted to beadjusted horizontally on said arch, which, when the shovel-beams areattached to them, will keep said beams parallel with the tongue of thecultivator, so that its shovels or plows will run near to and parallelwith the corn, and prevent said beams from being drawn inward and fromspreading their plows or shovels away from the corn.

The invention consists in certain novel features ofconstrnction andcombinations ofparts of the coupler, all as hereinafter described andclaimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in both figures.

Figure 1 is a perspective view of my improved coupler applied to acultivator, the lefthand half only of the axle and arch of thecultivator being shown in full lines, the shovelbeam and framebeamsbeing indicated by broken lines; and Fig. 2 is a plan view of the same,the beams being omitted.

The arch A and axle (a are of the construction common tohorse-cultivators. Sleeves B loosely encircle the bases of said archbetween the parts A and the axle, and clamps C D, also of the commonconstruction, are fitted upon said sleeves and connected,preferably, bybolts and nuts. The lower forward flanges of the clamps D are slightlylonger than the others, and are provided with proper apertures, e, forthe attachment of whifiletree-connections.

Curved arms E and straight arms E, each constructed with forked orbranching outer extremities, are respectively pivoted to the clamps G D,in the same plane therewith, by the bolts (1 d. The shovel-beams F areof the usual construction and are provided with shovels on plows of anysuitable form. Said beams are connected to the combined forkedextremitiesf g of the arms E E by bolts h, which are encircled bysleeves "i, permit-ting said beams to be swung toward or from the centerof the cultivator. Loops G are secured to the upper extremities of thearms E by the same bolts which connect said arms and shovel-beams, andare adapted to be engaged with chains or hooks depending from the frameof the cultivator, said frame and the tongue of the cultivator k k 76*being constructed and arranged in the ordinary manner.

The clamps O and D may be set and fixed at any desired places on thesleeves B by means of their connecting-bolts, and the shovel-beamshaving been placed at any desired distance from the plants to becultivated, by swinging said beams upon their pivotbolts the tighteningof the bolts 01, d, and it will establish a rigid bond of union between,the bases of the arch and said beams. Draftbeing applied to thecultivator, said beams will be maintained parallel with each other andthe tongue of the cultivator and at a uniform distance from the plantsunder cultivation. The sleeves B, being loosely fitted upon the bases ofthe arch and tightly grasped by the clamps, permit the shovel-beams tomove freely up and down and accommodate their plows or shovels toinequalities of the ground,

as Well as permit said beams to be connected by the loops G tosuspension devices attached to the frame of the cultivator when themachine is to be transported to another location. Having thus fullydescribed my invention, what I claim as new, and desire to secure byLetters Patent, is-

' 1. In a cultivator, the combination, with the arch provided with aloose sleeve upon each of its bases and adjustable clamps fitted uponsaid sleeves, of arms pivoted to said clamps and extending rearwardtherefrom in the same plane, one of said ar1ns,when in normalposition,beingapproximately parallel with the cutter of the cultivatorand the other curving inward toward the same, the extremities of saidarms being adapted to coincide and embrace the forward end of theshove1-beams,

whereby said beams may be swung toward or anddescribed and pivotallyconnected, rc from the center of the cultivator without despectively, tosaid shovel beams and said [O taching them from said clamps, as setforth. clamps, as and for the purposes set forth.

I 2. In a cultivator, the combination, with 5 the shovel-beams and thearch provided with PETER RADER' a loose sleeve on each of its bases andad- Witnesses:. justable clamps fitted upon said sleeves, of the WILLIAMD. FALL,

arms E and E, constructed as herein shown BYRON MoPHERsoN.
